Section 1: Lab: Getting Started with the Claude Free Plan for Office Work
What the Claude free plan offers: file upload, data analysis, and creating and editing Office files and PDFs
Turn on Code execution and file creation in Settings > Capabilities and use Projects to organise each piece of work
Usage limits that reset periodically, and why this course needs neither the Office add-ins nor Microsoft 365 Copilot
Lab: set up your account and create a Project for the BrightMart work
Section 2: Lab: Data Security and Responsible AI Use
Data you should not upload: personal data, ID numbers, customer records and confidential company information
Data masking and creating sample data before sending anything to AI
Hallucination and the principle that AI helps you think while people verify
Lab: mask sensitive columns in a sample file before uploading it
Section 3: Lab: Prompt Engineering for Data Work
Prompt structure: role, context, task, output format and constraints
Attach a data dictionary and ask the AI to check back when the data is unclear
Have the AI show its reasoning, formulas and assumptions so you can check them
Lab: write a reusable prompt template for sales analysis
Section 4: Lab: Checking and Summarising Data
Have AI check for blanks, duplicates and unusual date or number formats
Clean data with plain-language instructions and ask for a log of every change
Basic statistics: totals, averages, medians, minimum and maximum, and proportions
Lab: check and clean the BrightMart sales data
Section 5: Lab: Results, Trends and Basic Probability
Compare by branch, product category and period, with top and bottom rankings
Find trends with growth rates and moving averages, and forecast three scenarios
Estimate likelihood from historical data and tell correlation apart from cause and effect
Lab: find standout and problem branches and products, and forecast the next quarter
Section 6: Workshop: Having AI Create Excel, Word and PowerPoint Files
Excel: sheet names, columns, editable formulas, summary tables, charts and conditional formatting
Word: heading structure, length, Thai fonts, paper size and tables
PowerPoint: number of slides, slide titles, chart types and colour scheme
Check files after download, open them in desktop Office and fix Thai font issues
Workshop: produce an analysis workbook, a one-page Word summary and a three-slide summary deck for BrightMart
